Hantavirus in Older People: Symptoms, Risks, and Staying Safe at Home

Hantavirus is a rare but serious illness linked to rodents such as mice and rats. Cases in the UK are uncommon, and the overall risk to the public remains very low. Still, it can help for older people and families to understand the possible risks, symptoms, and ways to stay safe at home.

Older people, particularly those living with heart conditions, diabetes, breathing difficulties, or reduced mobility, may find it harder to recover from infections. Knowing what to look out for and taking practical steps at home can help lower the risk of illness and provide reassurance for families.

What is hantavirus?

Hantavirus is a virus spread mainly through contact with infected rodents or areas affected by rodent droppings, urine, or saliva.

Breathing in contaminated dust particles is thought to be the main way people become unwell.

This can happen when:

• Cleaning spaces where rodents have been present
• Disturbing dust in enclosed areas
• Touching affected surfaces and then touching the mouth, nose, or eyes
• Handling rodent waste without protection

Areas such as lofts, sheds, garages, cellars, caravans, and unused storage spaces may carry a higher risk if rodents are present.

Why can hantavirus be more serious for older people?

As we age, the immune system may not respond as strongly to infections. This can make recovery slower and increase the risk of complications.

For older people already managing health conditions, even flu-like illnesses can have a bigger impact on day-to-day wellbeing. In more serious cases, hantavirus can affect breathing and may need urgent medical care.

Families and carers should pay close attention to symptoms if a loved one may have been exposed to rodent-affected areas.

Common hantavirus symptoms

Early hantavirus symptoms can feel similar to flu and may include:

• Fever
• Headaches
• Muscle aches
• Tiredness
• Dizziness
• Nausea
• Chills

As the illness develops, symptoms can become more serious and may include:

• Shortness of breath
• Chest tightness
• Breathing difficulties

If an older person develops these symptoms after possible exposure to rodents or rodent waste, it’s important to seek medical advice quickly.

How to reduce the risk of hantavirus at home

There are several practical ways older people and families can lower the risk of exposure.

Check the home for signs of rodents

Look out for:

• Rodent droppings
• Chewed food packaging
• Scratching noises in walls or cupboards
• Nests in lofts, sheds, garages, or outbuildings

Seal small holes around doors, pipes, air vents, and brickwork to help stop rodents entering the property.

Clean safely

Avoid sweeping or vacuuming rodent droppings directly, as this can spread dust particles into the air.

Instead:

• Open windows before cleaning
• Wear gloves and, where possible, a well-fitting mask
• Spray the area with disinfectant first
• Wipe using disposable paper towels
• Place waste into a sealed bag before putting it in the bin
• Wash hands thoroughly afterwards

If an area is heavily affected, professional pest control or specialist cleaning support may be the safest option.

Store food properly

Keep food sealed and dispose of household rubbish regularly to reduce the chance of attracting rodents into the home.

Take extra care in unused spaces

Lofts, sheds, garages, caravans, and holiday homes can sometimes attract rodents if left unused for long periods. Older people should avoid cleaning heavily affected spaces alone where possible.

When should you seek medical advice?

Speak to a GP or contact NHS 111 if an older loved one develops flu-like symptoms after possible exposure to rodents or affected areas.

Seek urgent medical help by calling 999 or attending A&E if they experience:

• Difficulty breathing
• Chest pain
• Severe weakness
• Symptoms that suddenly worsen

Early support can make a real difference.
